Centuries-old ice samples extracted from western Greenland have raised new worries about the melting ice sheet and its potential contributions to global sea-level rise.

Global carbon emissions reached an all-time high in 2018, an extraordinary watermark in Earth's history that underscores the need for faster and stronger action to address accelerating climate change, according to dozens of scientists.

Wildfires, water shortages, agricultural damage — these are just a few of the risks that come with unusually hot, dry conditions. Scientists have warned that many regions around the world may be seeing more and more of this kind of weather as climate change continues to reshape the planet.

The Camp Fire, thought to be both the deadliest and most destructive California wildfire on record, has inspired many conversations about how climate change may be making such events worse.

Melting glaciers are some of the most conspicuous casualties of climate change, and for good reason: Meltwater from Greenland and Antarctica has dangerous potential to raise global sea levels as the climate warms.
